Question

ajuda por favooor a b e c

Answer 1

a)x - 1 / 2 + x - 3 /3 = 6/1   m.m.c = 6
3(x - 1 ) /6  +  2(x - 3 ) /6 = 36/6 cortar o denominador
3 x - 3 + 2 x -  6 = 36
5 x - 9  = 36
5 x = 36 + 9
5 x = 45
x = 45/5
x = 9
b)x -2 /3  -  x + 1/4 = 4/1  m.m.c = 12
4(x - 2) - 3 ( x + 1 ) =48
4 x - 8 - 3 x - 3 = 48
x = 48 + 11
x = 59
c)2 x - 3 /4 - (2 - x)/3 = x-1/3 m.m.c = 12
3(2 x - 3 ) - 4(2 - x) = 4(x - 1)
6 x - 9 - 8 + 4 x = 4 x - 4
10 x - 17 = 4 x - 4
10 x - 4 x = -4 + 17
6 x = 13
x = 13/6
